Description

EMI1.1
Die vorliegende Erfindung bezieht sich auf weitere Ausbildung der Schalung der Eisenbeton-RippendeLken. Die Einlage von Hohlkörpern aus biegsamen Stoffen oder aus Formsteinen auf ebener Schalung ist bekannt. Die Hohlkörper aus biegsamen Stoffen haben den Nachteil dass infolge ihrer geringen Widerstandskraft von einem ordnungsmässigen Stampfen der Rippen zwischen ihnen und der Platten über ihnen nicht die Rede sein kann, die so hergestellten Decken daher eine weit unter dem normalen Mass liegende Druckfestigkeit aufweisen.
Die aus Formsteinen bestehenden Hohlkörper zeigen infolge ihrer bedeutenden Sprödigkeit einerseits die gleichen Nachteile wie die vorigen, andrerseits zerbrechen sie auf dem Transport aus ebendemselben
EMI1.2
ohne sich namhaft durchzubiegen oder gar zu reissen. Es ist deshalb vorteilhaft, eine feste Asphalt Dachpappe, Rex Flint (ein imprägniertes Wollfilzmaterial), Eisenblech oder dgl. anzuwenden.
SelbstverständlichwirdderÜberzugidurchdasHolzgerippeinseinerWirksamkeitunterstützt, und man hat es in der Hand. durch einen entsprechend klein gewählten Abstand der Holzschablonen s die Tragfähigkeit nach Wunsch zu erhöhen.
Über den inneren Überzug t wird nun der äussere Überzug a angenagelt. Derselbe bestellt

indem er alle Hohl- und Zwischenräume desselben vollständig ausfüllt. Gleichzeitig ermöglicht der innere Überzug i ein ausreichendes Stampfen des Betons und verhütet den schädlichen
Wasserverlust.

EMI1.1
The present invention relates to a further embodiment of the formwork for the reinforced concrete ribbed ceiling. The inlay of hollow bodies made of flexible materials or shaped stones on flat formwork is known. The hollow bodies made of flexible materials have the disadvantage that, due to their low resistance, there is no question of proper tamping of the ribs between them and the plates above them, and the ceilings produced in this way therefore have a compressive strength that is far below normal.
The hollow bodies consisting of shaped stones show on the one hand the same disadvantages as the previous ones due to their significant brittleness, on the other hand they break from the same during transport
EMI1.2
without bending or even tearing. It is therefore advantageous to use a firm asphalt roofing felt, Rex Flint (an impregnated wool felt material), sheet iron or the like.
It goes without saying that the wood framework supports the coating and you have it in your hand. to increase the load-bearing capacity as required by selecting a correspondingly small spacing between the wooden templates.
The outer coating a is now nailed onto the inner coating t. The same ordered
EMI1.3
in that it completely fills all voids and spaces in between. At the same time, the inner coating i enables sufficient tamping of the concrete and prevents the harmful
Water loss.

If the reinforced concrete ceiling is to be designed with a flat soffit, then either the hollow bodies can also be closed on their underside in order to access the flat soffit thus created
EMI2.1
to attach.
